[Q] Wireless Charging + Daydream Bizarre Performance

This is my first experience with wireless charging so I'm probably missing the obvious here so please, anybody, point that out.
I'm newly using a wireless charger with my N5 & performance just doesn't make any sense to me. It's the Korean/Chinese knock-off of the N4 Orb which others on XDA have used successfully. On basic charging it does work but I can't make any sense of these numbers:
Charging I get roughly 10% per hour -- not great, but okay for bedside/overnight.
Charging with daydream on (Dashclock) on I get a loss of roughly 10% per hour! Yes, the phone keeps indicating it is charging in spite of this heavy drain.
But sometimes daydream just turns off & it returns to charging -- this seems to happen if I start off with the phone (mostly) charged. For the most part though, if I leave the phone on the charger overnight with daydream enabled I'll wake to a nearly empty battery.
As I said, these numbers make no sense to me at all. Part of the problem may be the power source for the orb - it's only 1A but even if it's underpowered I can't see the drop from +10% to -10% /hour.
Second part of my query -- does anyone know if it would be effective (and safe!) to feed 1.2A to the orb & maybe get faster charge. Or maybe that would be enough to keep up with the Daydream drain?
FWIW the the USB charger (1.2A) is very fast, I get better than 1% per minute -- unaffected by Daydream.

im using this and mine gets full charge within 1 and half hours

10% per hour? Something's wrong. A wireless charger shouldn't take much longer than wired.
It's possible your adapter is a dud. Try using the 1.2a adapter, it'll be fine. If it still isn't faster, you might have a bad charger.
Also, if it came with a USB cable, don't use it. The wires are too small to carry a reasonable amount of current.

So I'm using DashClock also and when it doesn't crash, my phone will charge just fine. Seems like about 3 hours total with daydream on, and about 2 hours with it off just regular charging. Here's my charger: http://www.amazon.com/gp/product/B00DOW1RD0/ref=wms_ohs_product?ie=UTF8&psc=1. Seems like you have a defective charger but it is a really weird situation.

Thanks guys, the jump to 1.2A made a world of difference! It still seems strange, but I guess there's a minimum threshold for the phone to properly charge. (I am really guessing!) Plugging the OEM charger into my qi orb I finally get a positive charge with daydream -- not fast, but good enough to wake with a charged phone! Without daydream I just got about 36% in the past hour.
A quick scan of eBay and the only 1.2A USB supplies I can find are refurbished LG & cost as much as the full qi orb! (from US with crazy shipping costs on these - I'm in Canada) But there are lots of 1.5A blocks, cheap (and free shipping from China). So... do you think it would be safe to try the 1.5A? According to Play the Google qi comes with a 1.8A supply but I have no idea how much the pad modulates the power or if that is all in the phone itself. It would be nice to have fast wireless charging, but with the dramatic jump with just the .2A increase I may be looking at something too powerful.
My concerns are (in order) 1. Don't want to fry the phone!
2. Don't want to burn down my apartment!
3. Would rather not trash the orb. The orb was inexpensive so I'm willing to gamble on point # 3.
Advice / assurances / suggestions? Please.

I assume you mean USB out from PC since OEM charger is USB and orb power supply is USB as well. Point taken on PC charging though.

The official orb charger comes with a 1.8a brick. You should be fine.

I mean if your orb uses a USB cable and came with one, don't use the cable it came with. They're often very cheap and add a lot of resistance which will increase charge time.
It wasn't the step up to 1.2A that made a world of difference, it's using a quality adapter that made the difference. Your 1A adapter must have been faulty or grossly overrated. Sounds like it was putting out less than 500mA.
As for a higher amperage power supply somehow damaging things? Not possible. The circuitry in the wireless charger is only going to use what it needs, you could hook it up to a 50A power supply and it'll still draw around 1A. The N5 is also input current limited to 1.2A, so using a crazy high amperage adapter won't have much benefit anyway.
Still, not a bad idea to get a 1.5A - 2A adapter to compensate for whatever current the wireless charger itself uses. This is probably why the official one includes a 1.8A adapter.

So from what I heard wireless charging, like a pogo plug can charge at a higher rate than the micro USB port in some devices (I've heard pogo plug can go up to 2.5A where the micro USB in that device is limited to 1.8A). So I'm wondering as these qi chargers get better, will this also be true. Mine is a 1A but seems like it charges around .8A so it's maxed out. I guess this also raises the question as to how fast is good for a battery also.

Need specific Car charger if anyone can help

I'm looking for a Car charger that can fast charge the V10 and also had a 1 amp output. Has anyone seen anything like this? All the dual car chargers I have seen that offer QC 2.0 have a second port that is 2 amps. I want to charge my phone and power my electronic cigarette that gets hot when using a 2 amp output.
Thanks

Get this one. Very good. Quick charge 2.0 on one then the other slot provides 2.4amp output for universal any device and even tablet could charge off it as well.

Did you read what I wrote? I specifically need one with a low amp second output as my electronic cigarette will not tolerate two amps.

Reason why I posted it, having read very well the op, I was having same issue and got this one which surprisingly works in my car.

I have the same one and it works without any problems. Perhaps you (OP) could reply in a better way instead of being snippy, he really did give you a good suggestion of what to get.

I'm sure it does work great, but i posted because I have a specific need and was hoping someone might know of a charger that could fill that need.

You won't find one. If it has QC , it will output more then 1a.

Look at Anker products, I have their "smart" charger. It adjusts to what is needed and supports quick change.

Regardless of smart or not, the device requiring the power will dictate how much amperage it draws unless charger or device is faulty up to the maximum available via the charger. Perhaps your ecig is very basic and is really meant to be used with a pc usb that doesn't supply more than 500mA and doesn't have the ic circuitry to cut and control it's own intake..
Like it has been mentioned for a charger to supply qc 2.0 it has to be rated at 1.8mA minimum, so most will be 2mA~
I spend a lot of time looking at chargers and havent seen any single that meets your requirements. I'd suggest getting a socket splitter and using two small chargers. One older 500-900mA and another qc 2.0.

get this one... 2.1 and 1A ports..

I wouldn't recommend anything but the cars port for the cig lighter.
Reason is, anything else that you plug that lighter into will be made partially out of plastic and will more than likely melt as the lighter heats up.

OP needs a lower output ( 1 Amp-500mA) to charge an electronic cigarette/vape mod and is not using the actual cigarette lighter. Honestly I would just advise that you remove the battery from your mod to charge because typically when mods fail it is either because a battery is being over-discharged (user error or mechanical short) or the IC circuitry fails causing the battery to vent. Charging your IMR batts in a dedicated charger tends to promote better daily use and overall extended life cycle. If you are still limited to keeping the battery installed in your mod while charging, is QC absolutely necessary? I personally have not ran into an issue topping off using a standard charger while driving.
EDIT: I thought the flux capacitor was a joke but looked it up and it actually fits your needs..
¯\_(ツ)_/¯

Charging currents

How would I know what the max current is a device can support like an accessory? So for example, the stock charger that comes with the Plantronics Voyager Edge is only 500ma. What happens if I plug it into a Qualcomm QuickCharge 2.0 charger like what comes with the S6? Will it blow up? Regulate down and charge normally? Charge rapidly?

it will charge normally. it doesnt matter how big the output of the charger is. the phone will regulate it to only what it wants.
only time you will have an issue is if your charger output is too small. the phone will charge slow, and risk damage to the charger.

Does this also apply to the headset I mentioned? How would the current being too low damage the charger? USB ports and car charger are very low current in general

1. yes
2. i didnt say it would damage the charger, i said there is a risk of it. thats because if its too small, the charger is working at maximum all the time.
3. usb's are regulated, not maxing out potential. im guessing car chargers do the same, however im not sure why. likely has something to do with a safe level considering the fluctuation in input voltage from the battery.

Hmm... So what about using a non-QC 2.0 charger (such as some that Anker make) on devices that support QC 2.0? Is there some safety issue or will it just charge slightly slower?

sorry, i dont know about those.
maybe you misunderstood before, i cant think of any common instance where there would be a safety issue.
as unlikely as it is that you will ever burn up a charger (or device for that matter), the only thing that will happen is some small electronic parts will go bad. not some huge fire or whatever. sure on the device there could be a nice exploding fire, but there about always from defect and also extremely rare. it happens maybe 1 or 2 times a year, and its gets posted everywhere, then people think its an epidemic and start asking all these unnecessary questions. im sure the yearly device sales are in the hundreds of millions work wide. if a couple a year blow up, well s happens.

long cable that doesn't slow charging time?

i am using a usb 3.0 extension cable, which is 15ft long. i notice charging is a bit slow when using the extension cable. i really want a long cable, the outlet layout in my room is weird. any cable that is 15 or even 10 feet long that doesn't interfere with charging time? or is this just a case of power attenuation?

I doubt you gonna find a cable like that... Also the power loss is normal for such a long cable. I still remember from my electronics class when the teacher told us, that the longer the cable is, the more power it looses

I think you can make 50m without big loss of power.

Have you tried measuring the charging current? You could try Ampere (http://forum.xda-developers.com/android/apps-games/app-ampere-charging-meter-t3012890) to see if there is a real difference when comparing short/long cables. Then also, you might want to check if the charger - assuming you are using a charger and not simply charging from your pc - gives you the maximum output (galaxy s5 charges with 1.8A max, so a 2A-Charger would fit your needs best).
Kind regards,
Kenny

Taking run-of-the-mill usb cables (inc usb 3) as using an average of 24 gauge wires for the power lines, that calculator shows that 5v DC has a 15% drop over 15 feet, giving an output of 4.23v at 1 amp, and a drop of almost 31% at 2 amps giving an out put of just 3.46v.
The OP would need to get a good quality cable using 20 gauge wires for the power lines to reduce the voltage drop at 1 amp by just 6% or at 2 amp by 12%.
http://www.amazon.co.uk/JuicEBitz®-Charger-Android-Tablets-BlackBerry-Black/dp/B010XWJBXQ
A cheap and nasty cable over 15 feet will absolutely hammer the output.
A better option would be to use a 15ft mains extension lead to move the outlet source closer and keep the usb lead on the charger to 5 or 6ft.

My bad, I missed the 'USB' part, was thinking OP was talking about purely a DC power adapter cable
I run CCTV cameras @ 20ft with 12v DC

They make these things called extension cords! we use AC for the simple reason that it travels over long distances well. Google Bell vs Westinghouse !

anyone who needs to ask will not know what "mains" means, see it all the time in 3d printing with the HBP's

You need a custom Kernel and a Rom Customizer app like Boeffla Config where you can set the Charging Current to a fixed value not depending on cable length

The best USB cables I've ever used come from a company called MediaBridge. You can get them on amazon for pretty cheap, and they are extremely high quality cables. I use a 10ft, and my phone charges just as fast as it does on a 4-ft cable.

Anker cables are great... faster then the oem cables.. substantially!

This cable it is specified as Faster Charging (Up To 2.4A).
But it product design this does not give me much of confidence, yesterday ordered one REMAX 2.4A(Max) this seems to have what needed for a six feet 2.4A cable.
The downside with REMAX this is flexibility, lots of copper inside makes it hard to twist it, or hide it when this crossing your office furniture.

Regarding REMAX cables, I need some help here from someone with Chinese education.
I need to find their exact cable specifications.
In the picture below they do mention some details, but I can not understand if they use metric or AWG.

Use a stronger Block

Large power block this is not needed.
People with technical background in electronics, them will possibly find as interesting my new article.
http://www.ittsb.eu/forum/index.php?topic=1153.0

I use these with 2A charger and get average of 1200mA charge. The guage of the wire is smaller (ie thicker) and it works!
So in summary 10 foot cable charging at over 1A.

You can't argue with the fact that it works. I have 4 of these and they all perform well. If you want to pay for it I would be happy to crack one open and test the gauge on it.

Warp charger advice

Can anyone let me know the risks, if any, of using the OP7 pro warp charger with other devices? I live in the UK if the voltage in matters.
I wanted to have one charger to charge my OP7pro, Sabatt e12 earphones and Nintendo Switch (undocked).
Anything I should think of? I don't know anything about voltages or fast charging. The headphones say to use a charger that is 5v/1a or "risk damaging".
Can anyone advise?
Thanks

Warp charge is 5v/6a, but whatever device you are charging should limit the voltage and amps. But ultimately yes you could damage your earphones.

It depends. Like Konfuzion has said, every device should have overvoltage protection or something, even earbuds. But it will be better (more safe) to use regular 5V/1A charger instead your Warp charger.

If your device use 5V as a power source, there shouldn't be any problem to use the Warp Charger. I've already used it to charge a Nintendo 2DS and Bluetooth devices and it charges normally, because is the device who control the power consumption (and therefore, the current)

Thanks. I figured because the instructions of the earbuds were specific that it might be a bigger risk.
Thanks. Appreciate the replies. Can I get any cables that would limit the charge? I ask because it would be easier to carry two cables and one plug than 2 plugs. Sorry if that is a stupid question. I know nothing about voltages and fast charging...which should be obvious by now ?

The old dash chargers I believe had some technology that negotiated with the phone before it put out the full amps, I'm pretty sure the warp chargers/cables have that too. When you plug your phone in, you will notice it doesn't warp charge immediately, it charges normally for a second then warp charges, so any device plugged in that can't negotiate with the charger should cap out at 2a,which is where the device your charging's protection comes in. You should be fine
Edit: be careful with your switch though, they are known to brick with 3rd party charges (google/youtube that) but it might have just been crappy 3rd party chargers, I don't have a switch to test

Actually, no. If you use a crappy cable, you could get (at least) the cable on fire (It won't happen, but technically is posible if you made your own cable with a very very thin conductor).
As I said before, is the device who limit the current at charging. In the case of the dash/warp charger, the cable has "a little extra" that allow the high current, and that is why you can't use any cable to get the dash/warp experience (if you want more info, read https://www.reddit.com/r/oneplus/comments/928iqn/whats_the_difference_between_dash_charge_cables/ )
